使用光強調變技術分析有機太陽能電池中雙分子複合機理研究

Using Solar Simulator light-dependent-techniques to analyze bi-molecule recombination in OPV. Recently, L. Zhong et al. demonstrate highly efficient ternary norfullerene OPV with two polymer donors and an organic acceptor. The results indicate that adding proper amount (20%) PTB7-Th polymer in the polymer donor could effectively improve in the ternary OPVs. Figure To illustrate the increasing of is due to the suppression of bimolecular recombination by PTB7-Th, they ...

How to precisely measure OPV/DSSC/Perovskite solar cells?

How to precisely measure OPV/DSSC/Perovskite solar cells? The efficiency of solar cells are evaluated in accordance withinternational standard called the Standard Test Conditions, STC (1000 W/m2of AM 1.5G and a cell temperature of 25℃). With the rapid development of the photovoltaic industry and advancement of material researches in solar cells, a stricter measurement method is needed for new type of solar cells compared to conventional crystalline silicon solar cells. This article introd...

What is PL?

What is PL? PL (Photoluminescence) is a non-destructive testing method, in which a substance absorbs high energy incoming photons and then re-emits photons of lower energy. By analyzing the photons emitting from the sample, many key information, such as material characteristics, carrier transmission route, or the carrier lifetime, can be elucidated when examining the PL spectrum. High-efficiency PL measurement systems are critical to the development of the nanomaterials, especially in the ...

What are QE and IPCE?

What are QE and IPCE? Quantum Efficiency, or IPCE (Incident Photon-to-electron Conversion Efficiency), is the conversion ratio of the incident photon to electron by a photovoltaic cell. For instance, if there are 100 photons irradiating on the surface of the solar cell and 80 electrons are generated, the Quantum Efficiency of the cell is 80%. Furthermore, because Quantum Efficiency is typically plotted as a curve related to wavelengths, it can also reflect the characteristics under variouw...
